For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] Example 1

[0025] Combined with appendix Figures 1-3 An enema device includes a storage bag 1, a catheter 2, an intestinal tube 3, and an anti-overflow device 4; the intestinal tube 3 is connected to the storage bag 1 through the catheter 2, and the catheter 2 is equipped with a switch 5, which allows the enema solution to be stored in the storage bag 1, the solution to enter the intestinal tube 3 along the catheter 2, and then enter the patient's body, and the opening and closing of the catheter 2 can be controlled by the switch 5.

[0026] An anti-overflow device 4 is fitted over the intestinal tube 3. The anti-overflow device 4 includes a fixed sleeve 4-1 fitted over the intestinal tube 3. It should be noted that the fixed sleeve 4-1 can move along the axis of the intestinal tube 3, so as to facilitate the adjustment of the length of the intestinal tube 3 inserted into the patient's body according to the actual situation. A sealing ring 4-7 is provided between the inner wall of the fixed sleeve 4-1 and the outer wall of the intestinal tube 3. The sealing ring 4-7 is embedded in the inner wall of the fixed sleeve 4-1, which can prevent the sealing ring 4-7 from accidentally falling out when adjusting the length of the intestinal tube 3 extending out of the fixed sleeve 4-1. At the same time, the sealing ring 4-7 can effectively increase the frictional resistance between the fixed sleeve 4-1 and the intestinal tube 3, thereby preventing the fixed sleeve 4-1 from moving freely within the intestinal tube 3.

[0027] The fixed sleeve 4-1 has a conical protrusion 4-2 at one end corresponding to the liquid outlet end of the intestinal tube 3. The fixed sleeve 4-1 is movably fitted with a movable sleeve 4-3. Between the movable sleeve 4-3 and the conical protrusion 4-2, there is an annular soft sac 4-4 that expands and protrudes outwards when squeezed.

[0028] In use, the intestinal tube 3 is inserted into the patient's anus until the circular soft balloon 4-4 is fully inserted. Then, the movable sleeve 4-3 is pushed to move closer to the conical protrusion 4-2. Under the combined compression of the movable sleeve 4-3 and the conical protrusion 4-2, the circular soft balloon 4-4 bulges and expands in all directions, thereby blocking the patient's anus and preventing overflow during the enema. After the enema is completed, the movable sleeve 4-3 is moved in the opposite direction, which shrinks the circular soft balloon 4-4 back to its original size, making it easy to remove the intestinal tube 3 and the anti-overflow device 4.

[0029] It should be noted that the diameter of the annular soft balloon 4-4 can be determined by the distance the movable sleeve 4-3 moves along the body of the fixed sleeve 4-1. That is, the closer the movable sleeve 4-3 is to the conical protrusion 4-2, the larger the diameter of the annular soft balloon 4-4 will be, so as to adjust the diameter of the annular soft balloon 4-4 according to the actual situation of the patient.

[0030] To ensure the structural strength of the annular soft balloon 4-4 after it bulges, multiple elastic strips 4-5 are provided circumferentially between the movable sleeve 4-3 and the conical protrusion 4-2 to support the annular soft balloon 4-4. That is, the elastic strips 4-5 are located inside the annular soft balloon 4-4. The elastic strips 4-5 bend and deform under the joint compression of the movable sleeve 4-3 and the conical protrusion 4-2, thereby supporting the annular soft balloon 4-4 and improving the reliability of the sealing.

[0031] A self-locking mechanism is provided between the end of the movable sleeve 4-3 away from the conical protrusion 4-2 and the fixed sleeve 4-1 to restrict the movement of the movable sleeve 4-3. That is, after the annular soft bag 4-4 ​​is expanded and adjusted to the correct position, the movable sleeve 4-3 can be locked by the self-locking mechanism to prevent the movable sleeve 4-3 from moving in the opposite direction and causing the annular soft bag 4-4 ​​to shrink and return to its original state.

[0032] The self-locking mechanism includes clamping arms 4-8 on both sides of the movable sleeve 4-3. The clamping arms 4-8 are hinged to the movable sleeve 4-3. The fixed sleeve 4-1 has multiple limiting grooves along its length that can cooperate with the clamping arms 4-8. The hinge shaft where the clamping arms 4-8 and the movable sleeve 4-3 are hinged is provided with a torsion spring for the clamping end of the clamping arm 4-8 to be engaged in the corresponding limiting groove. Under the action of the torsion spring, the clamping end of the clamping arm 4-8 can always be tightly attached to the fixed sleeve 4-1, thereby being able to be engaged in the corresponding limiting groove and achieving self-locking. After the enema operation is completed, the operator can press the handle end of the clamping arm 4-8, causing the clamping end of the clamping arm 4-8 to lift up and disengage from the corresponding limiting groove, thereby achieving the purpose of unlocking. After the self-locking mechanism is unlocked, the movable sleeve 4-3 can move freely along the fixed sleeve 4-1, causing the annular soft bag 4-4 ​​to shrink and return to its original shape.

[0033] To further improve the anti-overflow performance, the movable sleeve 4-3 is equipped with a shield 4-6, which can block the flow and prevent spraying during the enema operation.

[0034] Example 2

[0035] In actual operation, it was found that when the amount of medicine in the storage bag 1 is small, the flow rate of the medicine is slow and the flushing pressure is insufficient. In order to solve the above technical defects, this embodiment makes further improvements.

[0036] Combined with appendix Figure 1 An enema device, differing from Embodiment 1 in that, based on Embodiment 1, the catheter 2 is connected to a pressure balloon 7. The pressure balloon 7 has a one-way valve at one end corresponding to the storage bag 1, allowing the medication in the catheter 2 to continue flowing through the pressure balloon 7. Before the enema operation, some medication can be buffered in the pressure balloon 7. If insufficient flushing pressure occurs, the operator can squeeze the pressure balloon 7 to increase the medication flow rate and flushing pressure. A medication inlet connector 6 is located on one side of the top of the pressure balloon 7, allowing medication to be added to the pressure balloon 7 or other medications to be added.

[0037] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
